✨ Features

🌟 Core Features

• Bridge Operations: Enable asset transfers between the Polygon network and other chains.
• Smart Contract Deployment: Support rapid deployment and management of smart contracts on the Polygon network.
• Wallet Management: Provide unified wallet connection and balance query functions.

📋 Use Cases

1. Cross - Chain Bridging
   • Use bridge-operations.js for cross - chain operations such as asset transfers and token conversions.
2. Smart Contract Interaction
   • Utilize defi-interactions.js to interact with DeFi protocols, including lending, trading, and other operations.
3. Transaction Simulation
   • Use transaction-simulation.js to simulate transaction execution and avoid unnecessary transaction failures.

💻 Usage Examples

🚀 Starting the Server

node polygon-mcp.js

⚙️ Configuration Adjustment

Edit the config-manager.js file to modify the default configuration:

module.exports = {
  network: 'amoy',
  rpcUrl: process.env.POLYGON_AMOY_RPC,
  privateKey: process.env.PRIVATE_KEY,
  slippage: parseFloat(process.env.DEFAULT_SLIPPAGE) || 0.5,
  deadlineMinutes: parseInt(process.env.DEFAULT_DEADLINE_MINUTES) || 20
};
